F-series single acting triplex mud pumps are authorized by Continental Emsco Company to manufacture in China and fully conform to Continental Emsco Company’s technical requirement.

F-series mud pumps are rated at longer stroke length and relatively low stroke per minute. It can increase the service life of expendable parts of fluid end assembly.

The power end assembly mainly consists of frame, crankshaft and pinion shaft crosshead and extension rod. Frame is made of steel plates by welding and stress relieving treated to provide the optimum rigidity and high strength. Crankshaft is a hollow one piece steel casting. The power end utilizes the combination lubricating system of forced lubrication and splashing lubrication.

The fluid end assembly mainly consists of fluid end, valve assembly, liners and pistons. Fluid end is made of forged alloy steel and three fluid ends of each pump are interchangeable. The suction valve and discharge valve of F mud pump are interchangeable. Liners use Bi metal, the sleeve is made of wear resisting cast iron. Piston and piton rod are of slide fit and sealed with rubber seal rings and are fastened with lock nuts to prevent the piston from loosing.

The valve seat bores have bottom shoulders. The piston and liners are spray lubricated and cooled which allow an extended service life.
